Abstract

본 발명은 위성방송 수신기가 수신하는 위성방송 신호의 수신전계의 세기를 포시하는 것으로서 종래에는 위성방송수신 안테나의 설치시 전계강도를 측정할 수 있는 고가의 레벨메터나 스펙트럼 분석기등의 측정기기를 이용하여 안테나의 위치 및 각도를 조정해야 되었음은 물론 안테나의 설치시마다 설치위치로 고가의 측정기기를 운반해야 되었으며, 또한 측정기기를 구비하지 못한 일반 사용자들은 안테나의 설치가 매우 어려웠다.The present invention discloses the strength of an electric field of a satellite broadcasting signal received by a satellite broadcasting receiver. Conventionally, an expensive level meter or spectrum analyzer, such as a measuring instrument, can be used to measure electric field strength when a satellite broadcasting antenna is installed. Therefore, the position and angle of the antenna had to be adjusted, as well as the expensive measuring equipment had to be transported to the installation position every time the antenna was installed, and the general users who did not have the measuring equipment were very difficult to install the antenna.

본 발명은 수신전계의 세기에 따라 가변되는 고주파 AGC 신호를 이용하는 것으로 위성방송 튜너부가 출력하는 고주파 AGC 신호의 레벨을 판단하고, 수신한 위성방송 신호를 표시하는 TV 수상기 또는 모니터의 화면상에 판단한 고주파 AGC 신호의 레벨을 OSD(On Screen Display) 기능으로 표시함으로써 별도의 고가의 측정기기를 사용하지 않고서도 화면의 표시상태를 수신 전계의 세기를 정확히 판단하여 위성방송수신 안테나를 용이하게 설치할 수 있다.The present invention uses a high frequency AGC signal that is variable according to the strength of a received electric field, and determines the level of the high frequency AGC signal outputted by the satellite tuner, and determines the high frequency of the received television broadcasting or monitor. By displaying the level of the AGC signal with the OSD (On Screen Display) function, it is possible to easily install the satellite broadcasting receiving antenna by accurately determining the intensity of the electric field of the display state without using an expensive measuring device.
